Abstract (en)
A ceramic coating member with excellent rust prevention performance is provided. A ceramic coating member according to an embodiment of the present invention has a ceramic membrane arranged with ceramic fine particles on a metal substrate, wherein one-dimensional surface kurtosis (Rku) of the ceramic membrane is 3 or less, or two-dimensional surface kurtosis (Sku) is 3 or less, or 1 < (Rkub · Hvp)/Hvs < 6, in the case where one-dimensional interface kurtosis of a convexoconcave formed at an interface of the ceramic membrane and the metal substrate is defined as Rkub, a hardness of the metal substrate is defined as Hvs, and a hardness of the ceramic particles is defined as Hvp.
